As the factory catalyst breaks down, exhaust backpressure spikes and cross-flow efficiency drops, choking the naturally aspirated boxer engine. This restriction triggers stubborn P0420 diagnostic trouble codes (DTCs), reduces fuel economy, and compromises low-end torque delivery.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from corrosion-resistant heavy-gauge stainless steel, this direct-fit rear converter assembly is engineered specifically for the \u003cstrong\u003eFB20B\u003c\/strong\u003e engine platform. It features an advanced high-flow ceramic honeycomb substrate coated with precious metal catalyst materials to ensure thorough exhaust gas scrub without generating excess backpressure. Precision-machined, thick OE-style flanges and factory-correct hanger locations eliminate exhaust leaks and allow for seamless bolt-on installation without cutting, welding, or custom fabrication. Integrated hardware ensures tight mating to existing exhaust system joints.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2012-2016 Subaru Impreza 2.0L (Rear Position)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eFB20B\u003c\/strong\u003e \/ \u003cstrong\u003eGJ\u003c\/strong\u003e (Sedan), \u003cstrong\u003eGP\u003c\/strong\u003e (Hatchback)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e148 hp \/ 145 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\u003cstrong\u003eFCE55643\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2012-2016 Subaru Impreza 2.0i Base (Sedan \u0026amp; Hatchback)\u003c\/li\u003e\n  \u003cli\u003e2012-2016 Subaru Impreza 2.0i Premium (Sedan \u0026amp; Hatchback)\u003c\/li\u003e\n  \u003cli\u003e2012-2016 Subaru Impreza 2.0i Limited (Sedan \u0026amp; Hatchback)\u003c\/li\u003e\n  \u003cli\u003e2012-2016 Subaru Impreza 2.0i Sport Premium (Hatchback)\u003c\/li\u003e\n  \u003cli\u003e2012-2016 Subaru Impreza 2.0i Sport Limited (Hatchback)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GP\/GJ Impreza?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2012-2016 Subaru Impreza equipped with the \u003cstrong\u003eFB20B\u003c\/strong\u003e 2.0L engine across both \u003cstrong\u003eGJ\u003c\/strong\u003e sedan and \u003cstrong\u003eGP\u003c\/strong\u003e hatchback chassis.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this converter clear a P0420 catalytic efficiency code?\u003c\/strong\u003e\u003cbr\u003e Yes, when installed on a properly tuned engine with functioning oxygen sensors, this EPA-compliant unit restores nominal conversion efficiency to clear P0420 trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Boxer Caliber\u003c\/h3\u003e\n\u003cp\u003ePreserve the balance, fuel efficiency, and distinctive boxer engine acoustics of your Subaru.
